Abstract: A fuser, having a heater, a holder, and a first wire spring, is provided. The heater is in a form of a planar plate and has a first face and a second face. The holder has a supporting base supporting the first face of the heater. The first wire spring retain the heater on the holder. The first wire spring has a first facing portion, a first engageable portion, and a second engageable portion. The first facing portion faces and supports the second face of the heater. The first engageable portion and the second engageable portion extend from one and the other ends of the first facing portion. The first engageable portion and the second engageable portion are engageable with the holder in an end area on one side and an end area on the other side of the heater in a widthwise direction.

Abstract: A fuser having a heater, a belt, and a holder, is provided. The heater includes a metal-made base plate and a resistive-heating element and has a first face and a second face. The resistive-heating element is formed on at least one of the first face and the second face. The belt being an endless belt has an inner circumferential surface contacting the first face of the heater and rotates around the heater. The holder has a retainer face to contact the second face of the heater to retain the heater and a belt-guiding face to contact the inner circumferential surface of the belt and guide the belt there-along. The base plate has a pair of first edges located on one end and the other end of the first face in the widthwise direction extending in the lengthwise direction. The pair of first edges are rounded at ridges.

Abstract: A fuser having a heater, a holder, and a connector, is provided. The heater is in a form of a planar plate. The heater has a metal-made base plate having a recessed portion, a heating pattern having a resistance-heating element arranged on the base plate, and a plurality of power-supplying terminals conductive to the heating pattern. The plurality of power-supplying terminals are located in an end area in the heater on one side in a lengthwise direction of the heater. The holder supports the heater and has a projecting portion configured to contact the recessed portion in the lengthwise direction. The connector has electrodes connectable with the plurality of power-supplying terminals. The recessed portion is located between the heating pattern and one of the plurality of power-supplying terminals closest to the heating pattern in the lengthwise direction.

Abstract: A fuser, having a heater in a form of a planar plate and a holder supporting the heater, is provided. The heater has a first face and a second face opposite to the first face. The holder has a supporting base supporting the first face of the heater, a side wall protruding from the supporting base, a first contact portion, and a second contact portion. The first contact portion is located in an end area on one side in a lengthwise direction of the holder. The first contact portion protrudes from the side wall and contacts the second face of the heater. The second contact portion is located apart from the first contact portion in the lengthwise direction in an end area on the other side of the holder in the lengthwise direction. The second contact portion protrudes from the side wall and contacts the second face of the heater.

Abstract: A fixing device includes: a substrate; an endless belt rotatable around the substrate; a heating pattern including a heating resistor provided on the substrate; a terminal electrically continuous to the heating pattern and provided at an end portion of the substrate in a longitudinal direction of the substrate; a connector including an electrode connected to the terminal, the connector being mounted to the end portion of the substrate from one side of the substrate in a widthwise direction of the substrate and engaged with the substrate in the longitudinal direction to restrict movement of the connector with respect to the longitudinal direction; and an engaging member mounted to the connector from the other side of the substrate in the widthwise direction and engaged with the substrate in the longitudinal direction to restrict movement of the engaging member with respect to the longitudinal direction.

Abstract: An image forming apparatus, having a body, a fuser to fix an image on a recording medium by heat, an interface to accept a value for a first time, which is between an end of fixing by the fuser until entry into a low power-consuming condition for the heater, a fan, and a controller, is provided. The controller sets a second time being a predetermined length and subtract the second time from the first time to obtain a third time. If the third time is given a positive value, the controller continues driving the fan after the end of the fixing and throughout the third time, and inactivates the fan after the third time. If the third time is given a value smaller than or equal to zero, the controller inactivates the fan during the first time before the entry into the low power-consuming condition.

Abstract: An image forming apparatus includes a housing, a toner image forming portion, a foil transfer unit, a sheet tray, and a discharge portion. The toner image forming portion is provided in the housing and configured to form a toner image on a sheet. The foil transfer unit is configured to superpose a foil with a surface of the sheet. The sheet tray is installable in the housing in an inserting direction and configured to accommodate a sheet to be supplied to the toner image forming portion. The first discharge portion is configured to discharge the sheet from the foil transfer unit to the outside of the housing in a discharging direction opposite to the inserting direction. The second discharge portion is configured to discharge the sheet from the toner image forming portion to the outside of the housing without passing through the foil transfer unit in the discharge direction.
